切换ListViewes可见性会导致滚动问题

Question

我试图在一个地方设置两个ListViewes，一次只能看到其中一个。 （这是以编程方式设置的，具有setVisibility（View.GONE）） 第二个ListView可见后消失，第一个不滚动。我做了一些测试，并且发现，第二个ListView的onScrollListener总是捕获事件。 您是否知道如何设置它，总是可见的ListView的onScrollListener捕获事件？ 我已经尝试过requestFocus（），但它没有用。

这里有一些来自代码的sinpets：

public void toggle_services(View v) {
    if (home_services_detail.isShown()) {
        AnimationHelper.slide_up(this, home_services_detail);
        home_services_detail.setVisibility(View.GONE);
    } else {
        home_services_detail.setVisibility(View.VISIBLE);
        AnimationHelper.slide_down(this, home_services_detail);
        home_services_detail.requestFocus();

    }
    if (mobile_services_detail.isShown()) {
        AnimationHelper.slide_up(this, mobile_services_detail);
        mobile_services_detail.setVisibility(View.GONE);
    } else {
        mobile_services_detail.setVisibility(View.VISIBLE);
        AnimationHelper.slide_down(this, mobile_services_detail);
        home_services_detail.requestFocus();
    }
}

Answer 1

我设法解决了这个问题。我不知道为什么可见性改变会有奇怪的行为，所以毕竟我做了一个解决方案。 在代码中，之前有可见性改变，现在我从不应该在屏幕上的父级中删除布局并添加应该可见的布局。现在两个ListViews都完美运行。我认为它比可见性设置慢一点，但它正在运行。 有必要始终在屏幕上显示两个标题（mobile_services_title和home_services_title），这就是以编程方式设置布局参数的原因。

切换功能：

 public void toggle_services(View v){
        LinearLayout.LayoutParams bigWieght=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 11f);
        LinearLayout.LayoutParams smallWieght=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 1f);
        if(isHomeVisible){
            AnimationHelper.slide_up(this, home_services_detail);
            homeServicesLinearLayout.removeView(home_services_detail);
homeServicesLinearLayout.setLayoutParams(bigWieght);
            mobileServicesLinearLayout.addView(mobile_services_detail);
            AnimationHelper.slide_down(this, mobile_services_detail);
            mobileServicesLinearLayout.setLayoutParams(smallWieght);
        } else {
            AnimationHelper.slide_up(this, mobile_services_detail);
            mobileServicesLinearLayout.removeView(mobile_services_detail);
            mobileServicesLinearLayout.setLayoutParams(bigWieght);
            homeServicesLinearLayout.addView(home_services_detail);
            AnimationHelper.slide_down(this, home_services_detail);
            homeServicesLinearLayout.setLayoutParams(smallWieght);
        }
        isHomeVisible=!isHomeVisible;
    }
